Abstract

The number of smartphone users is increasing across various demographics, including students. With the presence of smartphones among students, it should be able to assist learners in enhancing their interest and understanding of mathematics effectively, anytime and anywhere. Therefore, this research aims to develop a mathematics learning media based on an Android application using PowerPoint and iSpring for set theory material for Grade VII students at Swadaya Tarus Private Junior High School that is valid, practical, and effective. The method employed in this research is research and development using the ADDIE development model: Analysis, Design, Development, Implementation, and Evaluation. Data for this research were obtained through interviews, questionnaires, and tests. The results of this research show that the set theory class application meets the criteria for valid, practical, and effective learning media for set theory material. The average total validity score from three validators is 4.34, indicating that the Android-based mathematics learning media falls into the valid category. The average practicality score from the large class teacher is 4.38, and the responses from the small-scale trial students were 4.6, while the responses from the large-scale trial students were 4.67, placing the Android-based mathematics learning media in the practical category. Additionally, the pass rate for small-scale trial students was 80%, and the pass rate for the large-scale trial students was 70%, indicating that the developed Android-based mathematics learning media falls into the effective category.

Abstract

The underlying issue addressed in this research is the low motivation and learning outcomes of students. This is attributed to the conventional teaching model, which is teacher-centered and the use of media that tends to make students passive and uninterested in the learning process. The aim of this study is to describe the improvement in motivation and learning outcomes of 8th-grade students at Catholic Junior High School Muder Teresa on cartesian coordinate material through discovery learning assisted by interactive powerpoint. The research method used is Classroom Action Research (CAR) using the Kemmis and McTaggart model, consisting og 4 stages, namely Planning, Impelemtation, Observation and reflection. Data collection techniques used include observation, interviews, questionnaires tests and documentation. Furthermore, the data were analyzed descriptively. The research result showed in the initial condition average motivation score of students at 53,86. Increasedto 70.5 in first cycle, and 79.64 in the second cycle. While the percentage of students who complated was 57.14% in the first cycle and second cyclewas 89.29%. Thus it can be concluded that the discovery learning model assisted by interactive powerpoint can improve the motivation and learning outcomes of 8th-grade students at Catholic Junior High School Muder Teresa on cartesian coordinate material. Keywords: Discovery Learning, Interactive Powerpoint, Learning Outcomes and Motivation

Abstract

This study aims to describe student’s mathematical reasoning abilities in solving trigonometry problems based on Gregorc thinking styles among XI students at SMA Negeri 1 Lobalain. The  research adopts a descriptive qualitative approach. Data collection techniques include thinking style questionnaires, test questions and interviews. The data analysis process follows the Miles and Huberman model, which consists of data reduction, data presentation and conclusion drawing. The results showed that, students with concrete sequential (SK) thinking style only fulfilled the indicators of presenting mathematical statements and using patterns and relationships to analyze mathematical situations. Students with abstract sequential (SA) thinking style are better at reasoning than students with other thinking style categories, but have not been able to fully compile and provide reasons for the correctness of the solution where abstract sequential thinkers are unable to provide reasons for the solution obtained from the problem. Students with a concrete random (AK) thinking style also did not fulfill all indicators of mathematical reasoning. They were only able to present mathematical statements and utilize patterns and relationships to analyze mathematical situations. Meanwhile, students with abstract random (AA) thinking style were only able to present mathematical statements.

Abstract

Differentiated learning is a learning approach designed to address the diverse learning needs of students. The aim of this research is to develop a learning design that is suitable for the varying levels of understanding and competency among students, and is effective in meeting the specific learning needs of students at SMP Negeri 17 Kota Kupang, particularly in comprehending the topics related to linear functions, specifically the subchapter on gradients. The research methodology employed is design research, which involves three stages: the preliminary stage (initial design), the implementation stage (experimentation), and the retrospective analysis stage (retrospective analysis). Data collection techniques and instruments used include tests (diagnostic assessment and formative assessment), interviews, and observations. The data analysis techniques employed encompass qualitative and quantitative descriptive analysis. This research yields a learning design that caters to students' needs and provides ample learning opportunities. Each activity in LKPD aids students in grasping concepts such as determining the gradient of a straight line passing through a central point and another point, finding the gradient of a line passing through two points, determining the gradient of a line from its equation, and applying these skills to solve real-life problems involving gradients. The research findings indicate an improvement in students' understanding and abilities, thus confirming the effectiveness of the developed learning design in enhancing students' learning outcomes. Keywords: Differentiated Learning, Linear Function
